Aircraft 25161

The average climb angle of the aircraft is 11 ° 20', and its average speed is 400 km / h. How long does it take to climb to a height of 3000m?

Correct answer:

t =  2.2899 min

Step-by-step explanation:

A=11+20/60=33411.3333  v=400 km/h m/s=400:3.6  m/s=111.11111 m/s h=3000 m  sinA=vvy  vy=v sinA=v sin11.333333333333° =111.1111 sin11.333333333333° =111.1111 0.196517=21.83518 m/s  t1=h/vy=3000/21.8352137.393 s  t=t1 min=t1:60  min=137.393:60  min=2.29 min=2.2899 min
